I've got problem with allow user to download file.

This is sending method:

class DownloadController < ApplicationController
def send
@headers["Content-Type"] =
("./public/files/"+params[ath]+"/"+params[:name]).content_type
send_file(("./public/files/"+params[ath]+"/"+params[:name]), :type =>
param[:name].content_type)
end
end

In view i have:

<%= link_to st, :controller => "download", :action => "send", ath => s,
:name => st %>

I get error:

Status: 500 Internal Server Error Content-Type: text/html 500 Internal
Server Error
